Routine prophylaxis is no longer recommended for most patients, including those with prosthetic joints. Appropriate implementation reduces unnecessary antibiotic exposure and helps combat antimicrobial resistance.

✅ Introduction
Antibiotic prophylaxis in dentistry has evolved substantially over the past two decades. Earlier protocols recommended antibiotics for a broad range of medical conditions. However, accumulating evidence demonstrated that the risk of adverse drug reactions and antimicrobial resistance often outweighs the potential benefit.
Today, prophylaxis is reserved for patients at the highest risk of adverse outcomes from infective endocarditis (IE) or for selected immunocompromised patients after consultation with the treating physician.

Among recommended agents, amoxicillin remains the first-line antibiotic, while clindamycin serves as an alternative in penicillin-allergic patients or specific resistant infections.

✅ Rationale for Dental Antibiotic Prophylaxis
Dental procedures that manipulate gingival tissues, the periapical region of teeth, or perforate the oral mucosa may produce transient bacteremia. In susceptible patients, these microorganisms can colonize damaged or prosthetic cardiac structures and lead to infective endocarditis.
The primary objective of prophylaxis is to reduce the incidence of severe systemic infections in high-risk individuals.

💬 Discussion
Dental antibiotic prophylaxis is now reserved for a narrowly defined population of high-risk patients. This evidence-based approach reflects the recognition that daily activities such as tooth brushing and mastication produce bacteremia more frequently than many dental procedures.
The most important preventive strategy remains excellent oral hygiene and regular professional dental care, which reduce chronic oral inflammation and the cumulative burden of bacteremia. In pediatric patients, adherence to weight-based dosing and confirmation of the cardiac diagnosis are essential for safe prescribing.

🎯Clinical Recommendations
▪️ Use antibiotic prophylaxis only for current AHA-approved cardiac indications.
▪️ Amoxicillin remains the first-line antibiotic for adults and children.
▪️ Verify allergies and calculate pediatric doses accurately.
▪️ Do not prescribe routine prophylaxis for prosthetic joint patients.
▪️ Promote antimicrobial stewardship and avoid unnecessary antibiotic exposure.
▪️ Emphasize preventive dental care and plaque control.

✍️ Conclusion
Dental antibiotic prophylaxis should be prescribed selectively and according to established guidelines. Current evidence supports its use primarily for patients at highest risk of infective endocarditis, including specific cardiac conditions in both adults and children.
Amoxicillin 2 g for adults and 50 mg/kg for children remains the standard regimen. Restricting prophylaxis to clearly indicated cases minimizes adverse events and supports responsible antibiotic use in dentistry.

Dental erosion in primary teeth has become increasingly prevalent due to changes in dietary habits and the growing incidence of systemic conditions associated with acid exposure. Unlike dental caries, erosion results from direct acid attack on enamel and dentin, independent of bacterial metabolism.

Primary teeth are more vulnerable because they exhibit:
▪️ Thinner enamel and dentin
▪️ Lower degree of mineralization
▪️ Higher organic content
▪️ Greater permeability
Untreated erosion may lead to accelerated tooth wear, pulpal complications, and compromised mastication and esthetics.

💬 Discussion
The prevalence of dental erosion in children has increased globally and is closely linked to modern dietary patterns and systemic disorders. Primary teeth are particularly susceptible because of their anatomical and compositional characteristics. The challenge for clinicians lies in differentiating erosion from other non-carious lesions and identifying the underlying cause.
Management should be multidisciplinary, involving pediatricians, gastroenterologists, nutritionists, and pediatric dentists when systemic conditions are suspected. Preventive interventions are highly effective when instituted early, whereas advanced lesions often require restorative rehabilitation.

🎯 Recommendations
▪️ Screen for erosive wear during every pediatric dental examination.
▪️ Record dietary and medical histories systematically.
▪️ Use the BEWE index for standardized assessment.
▪️ Apply fluoride varnish in at-risk children.
▪️ Educate caregivers about acidic beverages and feeding practices.
▪️ Refer children with signs of GERD or recurrent vomiting.
▪️ Schedule regular follow-up visits every 3–6 months.

✍️ Conclusion
Dental erosion in primary teeth is an increasingly recognized condition with significant clinical implications. Because deciduous teeth are structurally more vulnerable, early identification and management are critical. Control of etiologic factors, remineralization strategies, and minimally invasive restorative approaches are the foundation of successful treatment. Preventive education and interdisciplinary care are essential to preserve oral health and function in pediatric patients.
